I made Speedometer Pro for Wear OS: a GPS speedometer with 10 full-screen dials
Hi r/WearOS! I'm a solo developer. This started as a Garmin app that a few hundred people use, and I've now ported it to Wear OS.
It turns your watch into a real speedometer. GPS measures your speed every second, and the needle moves smoothly instead of jumping between readings.
What it does:
- 10 dial designs that fill the round screen: Classic, Vintage, Halo, Neon, Panel and more. Turn the crown to switch.
- km/h, mph, knots or m/s. The scale adapts to your top speed or stays fixed.
- Trip stats: distance, moving time, average and top speed. Your top speed also stays on the dial as a marker.
- Speed alert: the watch vibrates once when you go over your limit, and the dial shows a red zone.
- Keeps running when the screen turns off, and stops by itself after 20 minutes without moving.
- A tile with your last ride and one tap to start.
Privacy: your location never leaves the watch. No account, no ads, no tracking.
It's €0.99 on Google Play: https://play.google.com/store/apps/details?id=app.gerros.speedometer
Good for cycling, sailing, skating, or just checking how fast that train is going. I'd love feedback, especially on which dial you like and what you'd add next.
